I've searched around and haven't found the answer my questions. I started working for this client on April 1. They were using a firm that was outsourcing SEO to India. When I started, 67% of the traffic to the site was coming from India and page views were usually 1 and done (per Alexa). The backlinks are a lot of Indian and Middle Eastern directories that just pass links back and forth. The site had a PR4 when I picked it up. I cleaned up their outbound links (should I make these nofollow?) and I've worked to get some backlinks from a handful of PR4,5 and a couple 6.
Now, the Indian traffic is beginning to wane and the US traffic is on the rise. Overall site views are down, but individual page views are up to averaging 3. Time on the site is up 63% over the last month as well. The firm wasn't tracking sales, they were just blinding running PPC. We're tracking now and the only comparison I have to previous numbers are overall internet sales (which are up 61% since April 1). I stopped their Content Network ads this month that were wasting money and reallocated that money to paid search. Paid search revenues are double what they were last month(April) so far this month(May) (didn't have conversion tracking April 1-13).
PR is stuck on 4. I'm meeting with them next week to discuss where things are and where things are going. One of the issues they are concerned about is that the PR hasn't moved. I'm not sure what to tell them. We're targeting more keywords and we're having more success getting ranked and moving up with some of the less targeted keywords. I was telling my wife the other night that the growth over the last 2 months has been pretty solid and I think they should be happy with the results.
